KYIV, Ukraine—Ukrainian President Volodymyr Zelenskyy on June 27 urged Western leaders to supply anti-aircraft defense systems to his embattled nation as Russian forces assaulted Lysychansk, the last big city still held by Ukrainian troops in eastern Luhansk Province.
As the leaders met, Russian forces were bombarding Lysychansk, the Kremlin’s immediate battlefield target following the fall of neighboring Sievierodonetsk over the weekend.
